- NVRAM (Non Volatile RAM): It saves all the configuration folders.
- Flash: The flash is very necessary in a router because it carries all the memorized information.
- ROM: It carries information about the hardware.
- Console: The plug and the jacks of a router, they enable it to receive configurations.
- Interfaces: They enable the router to be connected to LAN and WAN.
